Description

Technical Field

[0001] The utility model relates to the technical field of chip testing, in particular to an aging board adjusting hook device. Background Art

[0002] Aging testing is the process of simulating the various factors involved in the actual use of the product to conduct corresponding conditions to strengthen the experiment. Common aging includes light aging, damp heat aging, and hot air aging. The product is used outdoors for a long time under sunlight. If you want to know the life span of the product outdoors, you need to simulate the ultraviolet light of the sun to conduct UV aging experiments. Of course, the intensity of the experiment is much greater than the actual outdoor light intensity, so as to shorten the test time. You can understand the aging of the product after how many years of use through a short test.

[0003] At present, after the chip is produced, in order to detect the quality of the chip, it is necessary to perform aging test on the chip. During the test, the chip is placed on the aging board and then enters the aging equipment for testing. When the traditional aging board enters and exits the aging board loading or unloading equipment, the cylinder sometimes cannot be withdrawn and the aging board needs to be pulled out manually. Manually pulling the aging board inside the equipment poses a safety risk, and sometimes the aging board is far away from the human operating position, so it is very difficult to pull the aging board. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content
